Do you let it drain into the hull or do you extract it?

I’ll add to this, my raptor has 6 summers on it so doing this service is on my list after reading this thread. I tested the coolant with a refractometer and it states the coolant mix was about 70/30 pg to water. The tag on the overflow tank said when filled in 2015 when manufactured it was tested to be 50/50. Just an interesting note on how the coolant changes over years of use.
I had a warranty issue on my heater last summer. Dealer drained the system, fixed the fitting, then replaced the coolant. I’m good.
The dealer also gave me the extra gallon they had. I keep it onboard, probably will never have low coolant now that I have that.
